Water Heater (I S E Water P R (C S ); Quipped ) - Jayco Jay Series Owner's Manual

pump is engineered by the OEM with a check
valve to prevent water from back flowing into
the fresh water supply tank
Fig. 7.3 Water pump strainer
Periodically check the in-line water pump
strainer for accumulated debris. To clean,
shut off the water pump, unscrew the clear
cap, remove the re-useable metal strainer and
clear any debris, then reinstall.
Water pump switch (optional)
When the water pump switch is ON the water
pump runs until 45 pounds of pressure has
been achieved. The red light will stay ON.
Turn the water pump switch OFF when it is
not in use.
The water pump switch should be in the
OFF position when
unattended for any amount of time. If
something would happen to the water
system, this may help limit water damage
to a smaller area.
Dry camping
When you want to use water in your RV and
the RV is not hooked up to city water, you will
need sufficient 12-volt DC power to run the
water pump.

Do not replace any component part with an
accessory part that is not authorized by the
water heater manufacturer, such as an
"add-on" electric heating element. Such
items are not approved to be installed and
could create an unsafe condition and will
void all warranties.

PLUMBING SYSTEMS
The water heater is designed to heat water
quickly and efficiently. The water heater
manufacturer has preset the sensing limit to
maintain the water temperature when the
water heater is activated. Hydrogen gas in the
water lines may result if you have not used
the water heater for two weeks or more. To
reduce the risk of injury under these
conditions, open the hot water faucet for
several minutes at the kitchen sink before you
use any electrical appliance connected to the
hot water system. If hydrogen is present, you
probably will hear an unusual sound such as
air escaping through the pipe as the water
begins to flow. Hydrogen gas may be present
even after water has been drained from the
tank. Open the sink faucet at the sink and
allow system to vent for five to ten minutes (or
as needed).
HYDROGEN GAS
FLAMMABLE. Do not smoke or have any
open flame near the open faucet. On DSI
water heater models make sure the interior
control switch is OFF during the above
listed procedure.
Odor from the hot water system
Many water supplies
amounts of sulfur to produce an odor, often
called "sulfur water." Sulfur water can be
caused by a chemical action or by bacteria.
Generally, sulfur water is not harmful, only
unpleasant to smell. To eliminate sulfur water
(or bacteria) sanitize the water heater. Odor
from sulfur water is not a service problem.
High altitude deration
Operation of the water heater at high altitudes
may require derating. Consult with your local
propane gas company, dealer or the water
heater OEM for proper derating of the water
heater. Change out of the orifice (derating)
should be done by your Dealer or a service
agency authorized by the water heater
manufacturer. It is important that once the RV
has returned to lower elevation any high
altitude deration or other adjustments be
reversed for proper operation of the water
heater.
